Programming Logic and Design
Final Exam Questions
Course Introduction
Programming Logic and Design introduces students to the fundamental concepts of computer programming, focusing on the development of logical thinking and problem-solving skills essential for software development. The course emphasizes structured programming techniques, such as the use of flowcharts, pseudocode, algorithms, and control structures like selection, iteration, and sequence. Students will learn how to analyze problems, break them into manageable steps, and design solutions that can be implemented in any programming language. By mastering these concepts, students build a strong foundation to understand how programs work and how to design efficient, error-free code.
